Yes
The device description explicitly states that it "utilizes artificial intelligence learning algorithms".

No
Explanation: A therapeutic device is used to treat a disease or condition. This device is an image processing software that assists in prioritizing cases of suspected intracranial hemorrhage, which is a diagnostic assistance function, not a therapeutic one.

No

The "Intended Use / Indications for Use" section explicitly states, "The output is intended for informational purposes only and is not intended for diagnostic use. The device does not alter the original medical image and is not intended to be used as a stand-alone diagnostic device."

Yes

The device description explicitly states it is "image processing software" and provides a "pipeline for the analysis and identification of potential ICH as well as a finding notification mechanism." There is no mention of any associated hardware components being part of the device itself.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • This device's function: syngo.CT Brain Hemorrhage processes medical images (CT scans of the head) that are already acquired from the patient. It does not analyze biological specimens.
  • Intended Use statement: The intended use clearly states it's designed to "assist the radiologist in prioritizing cases" and is "for informational purposes only and is not intended for diagnostic use." This further reinforces that it's not performing a diagnostic test on a biological sample.

Therefore, based on the provided information, syngo.CT Brain Hemorrhage is a medical image processing software, not an In Vitro Diagnostic device.

No
The provided document explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found". This means there is no mention of a PCCP being reviewed, approved, or cleared for this specific device.

The subject device syngo.CT Brain Hemorrhage does not have changes in fundamental scientific technology compared to the predicate device. The post-processing software functionality remains unchanged from the subject device and the predicate device. The operating principle and the scientific technology are the same; therefore, Siemens believes that syngo.CT Brain Hemorrhage application is substantially equivalent to the predicate device.

VI. Performance Data

The following performance data were provided in support of the substantial equivalence determination.

Non-Clinical Testing

Non-clinical tests (integration and functional) were conducted for syngo.CT Brain Hemorrhage during product development. These tests have been performed to test the ability of the included features of the subject device. The results of these tests demonstrate that the subject device performs as intended. The results of all conducted testing were found acceptable to support the claim of substantial equivalence.

Performance Evaluation of the Algorithm

The performance of the syngo.CT Brain Hemorrhage device has been validated in a retrospective standalone performance study. Sensitivity and specificity of syngo.CT Brain Hemorrhage in processing of non-contrast head CT have been analyzed by comparison to a ground truth established by majority read of 3 US board certified neuroradiologists with more than 10 years of experience. The data cohort consisted of 600 anonymized head CT cases from 5 sites in US and Europe with approximately equal distribution of positive (case with ICH) and negative (case without ICH) cases.

Sensitivity was observed to be 92.8% (95% CI: 89.3%-95.2%). Specificity was observed to be 94.5% (95% CI: 91.3%-96.5%). Thus, sensitivity and specificity exceeded the 80% performance goal.

The average per-case processing time was 13.67 seconds (95% CI: 7.48-19.86 seconds). This is comparable to the predicate device.

To conclude, syngo.CT Brain Hemorrhage is a safe and effective triage and notification device for intracranial hemorrhages which is substantially equivalent to the predicate device.
